Uses

Zafirlukast is used to prevent asthma symptoms and to decrease the number of asthma attacks in people 5 and older. It helps make breathing easier by reducing swelling (inflammation) in the airways. Regular use of this medication can help control your asthma, improve your ability to exercise, and decrease the number of times you need to use your rescue inhaler.

This medication works by blocking the activity of natural substances (leukotrienes) that may cause or worsen asthma. This medication does not work right away and is not used to treat sudden asthma attacks.
